Utils

pascalCase(str, opts?: { normalize })

Splits string and joins by PascalCase convention:

pascalCase("foo-bar_baz");
// FooBarBaz

Notice: If an uppercase letter is followed by other uppercase letters (like FooBAR), they are preserved. You can use { normalize: true } for strictly following pascalCase convention.

camelCase(str, opts?: { normalize })

Splits string and joins by camelCase convention:

camelCase("foo-bar_baz");
// fooBarBaz

kebabCase(str)

Splits string and joins by kebab-case convention:

kebabCase("fooBar_Baz");
// foo-bar-baz

Notice: It does not preserve case.

snakeCase

Splits string and joins by snake_case convention:

snakeCase("foo-barBaz");
// foo_bar_baz

flatCase

Splits string and joins by flatcase convention:

flatCase("foo-barBaz");
// foobarbaz

trainCase(str, opts?: { normalize })

Split string and joins by Train-Case (a.k.a. HTTP-Header-Case) convention:

trainCase("FooBARb");
// Foo-Ba-Rb

Notice: If an uppercase letter is followed by other uppercase letters (like WWWAuthenticate), they are preserved (=> WWW-Authenticate). You can use { normalize: true } for strictly only having the first letter uppercased.

titleCase(str, opts?: { normalize })

With Title Case all words are capitalized, except for minor words. A compact regex of common minor words (such as a, for, to) is used to automatically keep them lower case.

titleCase("this-IS-aTitle");
// This is a Title

upperFirst(str)

Converts first character to upper case:

upperFirst("hello world!");
// Hello world!

lowerFirst(str)

Converts first character to lower case:

lowerFirst("Hello world!");
// hello world!

splitByCase(str, splitters?)

• Splits string by the splitters provided (default: ['-', '_', '/', '.'])
• Splits when case changes from lower to upper or upper to lower
• Ignores numbers for case changes
• Case is preserved in returned value
• Is an irreversible function since splitters are omitted
